python实现html转ubb代码(html2ubb)

这两天在用python写一个采集器，有个功能模块是html代码转换为ubb，网上貌似没有现成程序，就自己写了个函数，顺便锻炼下自己的正则。

import re
def html2ubb(content):
	#以下是将html标签转为ubb标签
	pattern = re.compile( '<a href=\"([ss]+?)\"[^>]*>([ss]+?)</a>',re.i)
	content = pattern.sub(r'[url=1]2[/url]',content)
	pattern = re.compile( '<img[^>]+src=\"([^\"]+)\"[^>]*>',re.i)
	content = pattern.sub(r'[img]1[/img]',content)
	pattern = re.compile( '<strong>([ss]+?)</strong>',re.i)
	content = pattern.sub(r'[b]1[/b]',content)
	pattern = re.compile( '<font color=\"([ss]+?)\">([ss]+?)</font>',re.i)
	content = pattern.sub(r'[1]2[/1]',content)
	pattern = re.compile( '<[^>]*?>',re.i)
	content = pattern.sub('',content)
	#以下是将html转义字符转为普通字符
	content = content.replace('<','<')
	content = content.replace('>','>')
	content = content.replace('”','”')
	content = content.replace('“','“')
	content = content.replace('"','"')
	content = content.replace('©','©')
	content = content.replace('®','®')
	content = content.replace(' ',' ')
	content = content.replace('—','—')
	content = content.replace('–','–')
	content = content.replace('‹','‹')
	content = content.replace('›','›')
	content = content.replace('…','…')
	content = content.replace('&','&')
	return content

使用时直接调用html2ubb函数，返回值就是ubb码了html转ubb
